sam, I'm sorry that you had to have this conversation w/your wife at this time.
The things that your wife said are all in the mlc script. You've got to let her go and keep the focus on you and your family. Please try not to allow her to push your buttons. She knows exactly which buttons to push to get you to do what she wants. Step back and set some boundaries for your well being.
I can't even imagine having to deal w/her during this time, but you need to keep your focus on your family right now and supporting each other. There will be time enough upon your return home to focus on the separation/divorce.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
